The email has an attachment called report_625859705821.zip which in turn contains an exectuable report_{DIGIT[12]}.exe (which presumably is an error) which has a VirusTotal detection rate of 9/46. The Malwr report shows that this malware does various things, inclding an HTTP request to a hijacked GoDaddy domain at [donotclick]hubbywifeco.com/forum/viewtopic.php hosted on (Nuclear Fallout Enterprises, US) which is shared with another hijacked domain, hubbywifecakes.com.

From there, another executable is downloaded from one of the following locations:

This executable has an even lower detection rate of just 5/46. You can see the Malwr report for that here.

Blocking EXE-in-ZIP files like this at your perimeter is an excellent idea if you can do it.
